NUE .liER ELBOW.

Application filed November 9. 1517.

To (LM rfi/ioni t may concern.'

Be it known that 1, Lonnn .L (harris, a. citizen of the United States, residing at Evanston, in the county of Cool( and State of Illinois, ha ve invented a certain new and useful Improvement in dish-Conveyor l'lbows7 ot which the 'following is a full, clear. concise, and exact dcscriptifnl` reference be ing had to theI accompganying drawings. 'Forming a part ot' this specilicaimi.

'li-ly invention relates to ash conveyer s rs tenis. and more si with-ally 1o an improved elbow forming part oi an ash conveyer con fluit, and has for its gei'icral object thc provision o'l a practical and etlicient. elbow whose arms form an obtuse angle or au angle other than ninety degrees.

It is the primary object of the invention to provide an elbow of the class described, in which the wear of the parts is reduced to a minimum, and in accomplishing this object I provide the novel arrangement pointed out in the following description, in which reference is made to the accompanying drawings, wherein- Figure 1 is a vertical cross sectional view ot the elbow of my invention, showing parte oit the ash conveyer conduits attached thereto; and

Fig. 2 is :i vertical cross sectional view taken along' the line ot Fig. l, looking in. the direction. indicated by the arrows.

Similar characters of reference refer to similar parts in both views.

The improved elbow of my invention comprises a casing S having the substantially cylindrical portions 4 and 5 which together form an obtuse angle. The upper end 6 of the elbow is provided with the straight walls shown at 7 and 8 in Fig. 2. Between the straight. walls 7 and 8 and the cylindrical elbow, I provide the shoulders shown at 9 and 10 in Fig. 1. The upper side of the elbow between thc flange 11 and the end wall 12 is provided with an opening 13 arranged to be closed by the cover plate 14 held in place by the. screws 15-15. The shoulders 10 provided on the cylindrical portion 4 of. the-elbow are arranged to sup port the liners shown at 16 and 17. These liners, as most clearly shown in Fig. 1, are arranged parallel to the axis of the cylindrical portion 4 of the elbow. The shout ders 9 serve to support the liner 18, which lies in a plane normal to the axis of the cy- Specification of Letters Patent.

lindricalv portion D of the elbow; or, in other words. lies at right anglc-el to the conveyer ronduit 19, which is attached to the cylindrical portion 5. The flange 1l o't' the cylindrical portion -.lis connected with. the on\.'eyer conduit shown at 20, which extends outwardly and communicates with an ash tanti. lt desired, the cylindrical portion 4 may be provided with a throat liner 21. ln removing tln` liners, the cover plate 1l is renna-od and the liner 18 pulled upwardly ont o'lA the elbow. The liner lli may then be removed and the liner 1T moved downwardl) out ot the Hange ll. whereupon its removal i.:-er1nitted.

The opera-tion o1 the device is as follows: The ashes are projected through the pipe 19 'in the direction indicated by the arrow, and are caused to impinge against the liner 18. After striking this liner they are caused to pass outwardly through the cylindrical portion 4 ot' the elbow, and through the conduit 30 into the ash tank, from which the ashes may be removed into a vehicle. It will be observed that the wear on the liner 18 is reduced to a minimum due to the fact that it assumes a position at right angles to the flow oit the ashes. It the liner 18 were held in osition substantially parallel with thi` lincrf: 16 and 17. the ashes would strike the liner at an angle and wear out the` liner very rapidly. due to the wiping and cutting action of' the. ashes. Because of the location of the liner 18, as shown in Eig. 1 the ashes are caused to strike directly, without any cutting` action. and after striking the liner, they are caused by the steam which is utilized in the conveyer system to pass outwardly through the conveyer 20.

Although I have shown and described the liners 16, 17 and 21 as being provided in the section 4 of the elbow. I desire to have it understood that these need not necessarily be employed. since the wear in this section of the elbow is almost negligible.

Having thus described my invention, what I claim as new and desire. to secure by Letters Patent of the United States is:

1. An elbow comprising an intake conduit and an outlet conduit arranged at an anglev to said intake conduit, the inner side of said intake conduit and the adjacent side of said outlet conduit bein open and having the walls thereof extended to form side members provided with shoulders, wear liners supported by said shoulders at right angler,I to said intake conduit, and closing the open side of said outlet conduit respectively, the said last-named liners being held in lplace by said first-named liner, and means for holding said first-named liner in place.

2. An elbow comprising an intake conduit and an outlet conduit arranged at an angle to said intake conduit, the inner side of intake conduit and the adjacent side of said outlet conduitbeing open, Wear liners supported at right angles to said intake conduit and closing the open side of said outlet respectively, the said last-named liners being held in place by said firstnamed liner, and means for holding said first-named liner in place.

3. An elbow comprising an intake conduit and an outlet-'conduit' arranged at an angle to said intake conduit, the inner side of said intake conduit and the adjacent sid(` Copies of this patent may be obtained for of said outlet conduit being open, Wear liners supported at right anglee to said intake conduit and closmg the open side of said outlet respectively, the said last-named liners being held. in place by Said irstnamed liner.

4. An elbow comprising inlet and outlet conduits` joined at an angle, a removable Wear liner forming the outer side of' said outlet conduit, a Wear liner extending at an angle to said first-named wear liner, and closing the adjacent end of the intake conduit and extending at right angles thereto,

and a third liner held in place by said frstnamed wear liner.

In Witness whereof, l hereunto subscribe my naine this 5th day of November, 1917. LORNE A. GRIFFIN Witnesses:
